Halo has just released their popular colorful twin-rail tires in a 700c version designed for couriers. The tires come in black, white, purple, neon pink, neon green, and black/grey. The tires have an inverted tread that looks a little more grippy than your average road tires and also sport an anti-puncture center strip for flat protection. Halo claims the tires are extra thick and great for skidding. We’ll see how they hold up!
